Hi Nick,
My wife Michelle used to work with you at IGA She says hi.
Mate, the Hawkesbury is full of Jews, you just need to know where and when. It is true that they will turn up in most spots at one time or another, but there are spots that do hold fish on a regular basis. Expect many Pike Eels, Rays, Shovelnoses, Baby Hammerhead to be caught if you're soaking big slab baits, but you've gotta be in it to win it, I guess. You could try 6 inch Gulp grubs or 7 inch Gulp Jerk Shads, that will eliminate the pesty species being caught, although I did catch an Eel on a Powerbait Grub the other week.
Bring on Winter on the Hawkesbury, my favourite time of the year for Jews.
Mick
